THOMAS DAVIS, OF ST. PAUL, MINNESOTA.

RADIATOR.

SPECIFICATION forming part of Letters Patent No. 266,979, dated November '7, 1882.

Application filed May 29, 1882.

To all whom it may concern:

Be it known that I, THOMAS DAVIS, a citizen of the United States, and a resident ot St. Paul, in the county of Ramsey and State ot' Minnesota, have made certain new and useful Improvements in Radiators, of which the following is a specification.

This invention relates to radiators used in systems of steam or hot-air heating; and it consists in the construction and arrangement of parts, substantially as shown and specitically described. i

In the drawings, Figure l isasideelevation. Fig. 2 is an end elevation; and Fig. 3 is a plan View, partially in section, the right-hand lower halt' et' Fig. 2 being in section on the line y y of Fig. 1. Fig. 4 is a cross-section of the base on the line wx of Fig. 1. Fig. is an enlarged horizontal section of a portion of one end of the base and the valves.

A is the base, and B the steam-pipes, constructed in any well-known manner, except that a transverse partition, a., is formed in the base near one end, thereby producing a compartment, b, and the remainder of theinterior ofthe base is divided by horizontal partitions i cinto as many compartmeu ts d as there are horizontal rows of the pipes B running from end to end of the base A,each rowot pipesthus opening down into a separate compartment d, the base A and partitions t c being all cast in one piece..

Through thetransverse pa1ti;ion a,opposite each compartment d, brass valve-seats e (see Fig. 5) arescrewed,in which valvesg are seated, the stems 71J ofthe valves ruiming out through screw stuting-boxes Din the base A,and ending with hand-wheels E, by which the valves may be operated to open or close communication between the compartment b and compartments d.

(No model.)

The openings through the end of the base A for the stuffing-boxesDwill belarge enough to permit'the valve-seats e to be inserted through them and fitted into their places.

F is the main steam-supply pipe, which is arranged to lead into the compartment b from any point. By this arrangement the radiator is divided into as many separate sections as there are horizontal rows of pipes, and each section is provided with its own steam-supply compartment d and controlled by its own valve, so that any separate section may he supplied with steam or cut oft' at pleasure. Thus all or only a portion of the radiator may be used, which will be a very useful feature when it is required to reduce or increase the temperature, or when only'a moderate degree of heat is required.

I am aware that it is not new to construct a steam-radiator with two or more rows ot' tubes, each row having its ownsteam-chamber, valve`inlet and outlet, and I lay no claim thereto; but

In a radiator, a base, A, divided by partitions cinto a series of compartments, d, and by transverse partition a into an end compartment, b, in combination with independent rows ot pipes B, opening into compartments d, supply-pipe F, and valves g, passing through compartment b, and controlling communication between compartments b and d through partition a, substantially as set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

THOMAS DAvIs.
